Soden refers, without much excitement, to a boiling commotion, but the results of Kelly's "air-boiling" were, evidently, not such as to impress the rest of those who claimed to have seen his furnace in operation. Only five of the total of eighteen of the witnesses say that they witnessed the operations.
Following this he made what is now called a "converter," in which he could refine fifteen hundred pounds of metal in five minutes, effecting a great saving in time and fuel, and in his little establishment the old processes were thenceforth dispensed with. It was locally known as "Kelley's air-boiling process."

Soden, incidentally, knew of seven different "air-boiling" furnaces, some with four and some with eight tuyères, but he also neglected to report on the use of the metal. Bessemer, op. cit.
